feel like I'm losing my s**t

I have been with my boyfriend for almost 2 years (known each other been friends for 11yrs). we have a son who turns 1 on Sunday (Literally days away). and my due date with our second son is Nov 13th. I woke up Monday morning and had this cramping in my stomach and lower back. I figured because baby is low that's why. i get kids off to school I get lunch then ready for work (I work for boys and girls club so after school hours) and play a little with my youngest. I leave for work and driving into work it's hurting more and more still cramps but stronger. long story short I was kept over night in l&d; because I had uti but my ffn came back positive so I had to receive shots of steroid and shots to stop the irregular contractions I was having. now when I am supposed to be resting not stressing my boyfriend wants to accuse me of talking to my ex. all because we were at the same funeral two weeks ago. I have clothes to wash, car seat to wash, bags to pack, diapers to get, and a name to figure out. my son could come anytime and doesn't have a name yet like not even an idea. feel like I'm losing my s**t and I'm failing at life. Sorry just needed to vent.
